Configuring and Using Backup Devices
Shared Devices in the SAN Environment
Chapter 2
53
The drive naming convention shows its benefits during backup
specification creation. Whenever you configure a backup on any host, all
you have to do now is to use the drive that is configured on that host,
since the drive includes the host name in its name.
Defining Lock
Names
Using
Lock Names
is necessary in a SAN environment. This prevents
collisions on the device caused by several systems talking to it at the
same time. It is recommended to use the following convention for
Lock
Names
:
LibraryLogicalName_DdriveIndex
, for example
SAN_LIB_D1.
